摘要： The present invention relates to a ball chain used by being integrated to, for example, a ball endless track of a linear guide device for endless sliding in which a number of balls are arranged in one row and rollably held, particularly to a ball chain which is most pertinent to a linear guide device having a ball rolling groove in a shape of a Gothic arch. According to the ball chain, the number of balls are arranged in one row and the balls are held rollably, each of the balls is pinched by a pair of spherical seats and the spherical seats are connected to each other by flange portions to thereby constitute a ball holding unit and a plurality of the ball holding units are connected in a shape of a rosary by a flexible connecting portion. Further, the spherical seats and the flange portions are molded by a resin material whereas the connecting portion is formed by a material having a tensile strength larger than that of the resin material.

摘要： In a roller retainer assembly, a roller retainer 15 is thinned to retain individual one of plural rollers 7 circulating in a roller circulation path inclusive of linear and curved races and to hold opposite side surfaces of the roller 7 and front and rear surfaces thereof in the roller moving direction. A combination of linear and curve guide portions 16a and 16b different in inclination angle and a combination of linear and curve guide portion 17a and 17b different in inclination angle are formed respectively in opposite end surfaces of the roller retainer 15 in a retainer moving direction. In a linear race, the linear guide portions 16a and 17a come into contact with adjacent roller retainers 15 respectively. In a curved race, the curve guide portions 16b and 17b come into contact with adjacent roller retainers 15 respectively.

摘要： A sealing member for a rolling device is applied to a rolling device with inner and outer members and a plurality of rolling members between so the rolling members can roll to allow relative rotational or linear movement of the outer member with respect to the inner member. The sealing member includes an inner and outer lip parts that press the inner and outer members, respectively. The outer lip part is less rigid than the inner lip part. The sealing member may have a substantially circular shape and surround the inner member. Alternatively, the sealing member may have a substantially plate-like shape and extend in a direction of relative movement of the outer member with respect to the inner member. The sealing member for a rolling device configured as described above and a rolling device provided with the sealing member can be adequately used even in a hostile environment.
